I hope to be able to keep working during the Easter vacation f , and tor 

 look over the material', and to finish the drawings.. I shall' restrict- 

 myself at first to the american pines, and not publish at first the 

 europaean and asiatic ones.. I amjln the clear with them with exceptiorr 

 of some indianybut the illustrations delay me, and I f d rather work 

 with your pines, which cause so much labofco.Once the illustrations have 

 been cleared. awayy I will 1 Council with you about loaalities and de^i - 

 ationsy and ask you, to make possible the publication in an americanr 

 journal. Because, I do not give up hope, to corae as professor, once 

 a forestry academy has been^ founded in America» Though my English has 

 been somewhat neßclected, this would soon i improve. and my pronunciation 

 is #ood^,as I had much oportunity to speak with English people in my 

 youth.lt is for that reason, that I would like to publish special ame-

 time, as I received from Vienna the request,to send to Philadelphia- 

 similar material as was exhibited by our school? in 1873 in Vienna«. 

 As I have absolutely no time to undertake suchr work , I declined. . La -

 easily produced- material through my students.., and could have exhibi- 

 ted on my own. . But for this it is too late, and I have no time.. The 

 diagrams, which I produced, are already discolored" and have to be made 

 anew. These are specimens of branches with flowers and cones- of 

 spruce, pines, fir" with enlarged flowers and anatomy of needle,the cones, 

 scales, roots, bark and wood. Further damaged parts with injurious- 

 insects and mounted caterpillars. . Collections of buds in srlass-tubes, . 

 mud-soils of different rocks. Graphic .metereological demonstrations, 

 Tel^f cards to be assembled to show the layers of rock formations,. 

 and wax-modelled anatomies of flowers that can be taken apart,. Much of 

 this got stuck in Vienna in 1873» and had to be made entirely new. . For
